Past investigations into the heavy fermion compound CeAl$_{3}$ reveal a
complex low-temperature physics resulting from the strong hybridization of
localized 4f states with delocalized conduction electrons. This phenomenon
gives rise to unusual electronic, thermal, and magnetic properties. We
investigate the low-temperature thermoelectric properties of this strongly
correlated system for its potential application as a $p$-type Peltier cooling
element. In our work, nanostructured samples of CeAl$_{3}$ have been
prepared using dc hot-press method and evaluated for their thermoelectric
properties. Effects of different hot-pressing temperatures on the
nanostructure and the thermoelectric properties will be discussed. Our
results on CeAl$_{3}$ will be compared with our previous work on CeCu$_{6}$.
